The Department of Homeland Security is utilizing post-9/11 investigative authorities to monitor community organizers. This campaign represents a significant escalation in federal oversight, drawing comparisons to counterinsurgency efforts from the 1960s and 1970s. ## Project Whipple and Puppet Master Investigations known as Project Whipple Shield and Operation Puppet Master operate under the National Security Presidential Memorandum 7. This directive authorizes federal law enforcement to deploy extensive resources against organizations critical of administration policies. The full scope of these investigations remains largely unknown, despite the emergence of numerous audio transcripts and emails. ## Repurposing Criminal Investigation Funds Operation Keyhole, originally established in 2008 to fund narcotics and child abuse investigations, now bankrolls the Minnesota 15 prosecution. HSI agents have repurposed these financial mechanisms to target domestic dissenters. As of June 2026, the program was underwriting six active undercover investigations within the Minneapolis–Saint Paul metropolitan area alone. ## Militarized Enforcement and Infiltration Approximately 120 HSI agents, including 11 undercover operatives, were assigned to the Minnesota case. These agents infiltrated churches and activist training sessions to gather intelligence. The operation utilized highly invasive techniques, including the deployment of Reaper drones and Patriot Act tools typically reserved for terrorism and complex money laundering investigations. ## The Minnesota 15 Indictment The indictment follows the administration’s Operation Metro Surge, which sought to suppress community response networks. Prosecutors allege that activists engaged in a conspiracy to stalk and identify federal agents using encrypted Signal groups. Defense attorneys argue these charges are disproportionate, noting that the defendants were involved in public speaking tours. ## Certified Undercover Oversight Operation Keyhole operates under the CUC designation, requiring formal oversight and reporting procedures. A committee of senior DOJ and DHS officials reviews the program parameters every six months. Despite these internal checks, the program has expanded its focus from traditional criminal probes to include the monitoring of domestic political dissenters. ## Digital and Physical Surveillance HSI teams conducted extensive surveillance across multiple cities, including Seattle, Chicago, and New York. Agents photographed vehicles and monitored license plates at activist meeting locations. Furthermore, the investigation involved the analysis of 15 terabytes of Signal chat data, providing a comprehensive view of the activists' internal communications and organizational structures. ## Advanced Data Fusion Techniques Investigators utilized commercial data brokers and DNS queries to deanonymize activists. By fusing SSH session logs with Minnesota DVS records and Thomson-Reuters CLEAR platform data, agents obtained Social Security numbers and property histories. This digital forensic approach allowed the government to link online activity to specific individuals under investigation for dissent. ## Cross-Jurisdictional Agent Involvement The investigation drew upon HSI agents with experience in financial fraud and organized crime from across the country. Several agents involved in the Minnesota case have histories of high-profile confrontations with activists in Los Angeles and other cities. This suggests a coordinated, nationwide effort to suppress anti-ICE movements through specialized units. ## Historical Parallels and Implications Experts compare these tactics to the FBI’s COINTELPRO, noting that the current scale of surveillance is significantly larger. By leveraging administrative summons and financial reporting programs, the DHS has created an intelligence apparatus that operates in parallel to traditional law enforcement. This shift signals a new era of domestic federal monitoring. ## Sources covering this story - https://www.wired.com/story/ice-is-running-one-of-the-largest-anti-left-surveillance-operations-in-us-history/ — --- _Summary written by Brifing from the original reporting.
